Estimate what a competitor's ads cost.

Networks publish reach, never budgets. Evidio turns an ad's published reach into a spend range and a daily figure, and says how confident the estimate is.

  • What you can see

    • An estimated spend per ad, as a range marked with ≈
    • An estimate per day the ad has run
    • The reach the network published, and whether it is exact or a bracket
    • A confidence level, low or medium
    • Meta ads shown in the EU and TikTok ads with a published reach

    You get an order of magnitude for an ad's budget, with its assumptions in plain view.

    How it works

    From published reach to spend range.

    1. Open a store's ads

      Estimates appear on ads whose reach the network publishes.

    2. Evidio models the delivery

      Reach times an assumed frequency gives impressions; a typical cost per thousand gives the spend.

    3. Read the range

      A low and a high figure for the ad, a figure per day, and the confidence level.

    When it helps

    Size a competitor's ad effort without guessing.

    The situation

    You see a competitor's ad everywhere and wonder whether it costs them a hundred euros or ten thousand. The ad library shows the ad, never the budget.

    With Evidio

    The ad's published reach becomes a spend range with its assumptions. You know the order of magnitude, and how much weight the figure can bear.

    Questions it helps answer

    • Roughly how much has this ad cost?
    • Is this a small test or a large campaign?
    • How reliable is the estimate?
    Read the signal correctly

    An estimate built on stated assumptions.

    Spend is modelled from the reach Meta publishes for ads shown in the EU, or the reach bracket TikTok publishes, with an assumed frequency and cost per thousand impressions. Real costs vary widely by market and audience. Confidence is medium at best, there is no estimate without published reach, so none for Google ads, and there is no store-level total.

    • The dates the ad ran

    Estimated or inferred

    • Impressions, from an assumed frequency

    Frequently asked questions

    How is the spend estimated?

    Published reach multiplied by an assumed frequency gives impressions; impressions multiplied by a typical cost per thousand give a spend range. Meta and TikTok use different assumptions.

    Why do some ads have no estimate?

    An estimate needs a published reach. Meta publishes it for ads shown in the European Union, TikTok as a bracket, and Google not at all.

    Can I see a store's total monthly ad spend?

    No. Estimates are per ad. Adding them up would stack assumptions, and Evidio does not present that as a store budget.
